From a3d0b1218d351c6e6f3cea36abe22236a08cb246 Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Wed, 26 Mar 2014 19:37:21 -0400 Subject: [PATCH] drm/nouveau/acpi: allow non-optimus setups to load vbios from acpi There appear to be a crop of new hardware where the vbios is not available from PROM/PRAMIN, but there is a valid _ROM method in ACPI. The data read from PCIROM almost invariably contains invalid instructions (still has the x86 opcodes), which makes this a low-risk way to try to obtain a valid vbios image.
